Baicalin, silver titanate, Bletilla striata polysaccharide and carboxymethyl chitosan in a porous sponge dressing for burn wound healing
Objective
This study tests the efficacy of Bletilla striata polysaccharide (BSP), carboxymethyl chitosan (CMC), baicalin (BA) and silver titanate (ST) in a wound dressings to fight infection, promote healing and provide superior biocompatibility.
Methods
The antibacterial activity of BA and ST was evaluated in vitro using the inhibition zone method. BA/ST/BSP/CMC porous sponge dressings were prepared and characterized. The biocompatibility of BA/ST/BSP/CMC was assessed using the cell counting kit-8 assay. The therapeutic effect of BA/ST/BSP/CMC was further investigated using the dorsal skin burn model in Sprague-Dawley rats.
Results
The wound dressing had good antibacterial activity against Escherichia coli and Staphylococcus aureus through BA and ST, while the combination of BSP and CMC played an important role in promoting wound healing. The BA/ST/BSP/CMC porous sponge dressings were prepared using a freeze-drying method with the concentrations of BA and ST at 20 and 0.83 mg/mL, respectively, and the optimal ratio of 5% BSP to 4% CMC was 1:3. The average porosity, water absorption and air permeability of BA/ST/BSP/CMC porous sponge dressings were measured to be 90.43%, 746.1% and 66.60%, respectively. After treatment for 3 and 7 days, the healing rates of the BA/ST/BSP/CMC group and BA/BSP/CMC group were significantly higher than those of the normal saline (NS) group and silver sulfadiazine (SSD) group (P < 0.05). Interleukin-1β expression in the BA/ST/BSP/CMC group at 1 and 3 days was significantly lower than that in the other three groups (P < 0.05). After being treated for 3 days, vascular endothelial growth factor expression in the BA/BSP/CMC group and BA/ST/BSP/CMC group was significantly higher than that in the NS group and SSD group (P < 0.05). Inspection of histological sections showed that the BA/ST/BSP/CMC group and BA/BSP/CMC group began to develop scabbing and peeling of damaged skin after 3 days of treatment, indicating accelerated healing relative to the NS group and SSD group.
Conclusion
The optimized concentration of BA/ST/BSP/CMC dressing was as follows: 6 mg BSP, 14.4 mg CMC, 0.5 mg ST and 12 mg BA. The BA/ST/BSP/CMC dressing, containing antibacterial constituents, was non-cytotoxic and effective in accelerating the healing of burn wounds, making it a promising candidate for wound healing.

期刊介绍：
The predecessor of JIM is the Journal of Chinese Integrative Medicine (Zhong Xi Yi Jie He Xue Bao). With this new, English-language publication, we are committed to make JIM an international platform for publishing high-quality papers on complementary and alternative medicine (CAM) and an open forum in which the different professions and international scholarly communities can exchange views, share research and their clinical experience, discuss CAM education, and confer about issues and problems in our various disciplines and in CAM as a whole in order to promote integrative medicine.
JIM is indexed/abstracted in: MEDLINE/PubMed, ScienceDirect, Emerging Sources Citation Index (ESCI), Scopus, Embase, Chemical Abstracts (CA), CAB Abstracts, EBSCO, WPRIM, JST China, Chinese Science Citation Database (CSCD), and China National Knowledge Infrastructure (CNKI).
JIM Editorial Office uses ThomsonReuters ScholarOne Manuscripts as submitting and review system (submission link: http://mc03.manuscriptcentral.com/jcim-en).
JIM is published bimonthly. Manuscripts submitted to JIM should be written in English. Article types include but are not limited to randomized controlled and pragmatic trials, translational and patient-centered effectiveness outcome studies, case series and reports, clinical trial protocols, preclinical and basic science studies, systematic reviews and meta-analyses, papers on methodology and CAM history or education, conference proceedings, editorials, commentaries, short communications, book reviews, and letters to the editor.
Our purpose is to publish a prestigious international journal for studies in integrative medicine. To achieve this aim, we seek to publish high-quality papers on any aspects of integrative medicine, such as acupuncture and traditional Chinese medicine, Ayurveda medicine, herbal medicine, homeopathy, nutrition, chiropractic, mind-body medicine, taichi, qigong, meditation, and any other modalities of CAM; our commitment to international scope ensures that research and progress from all regions of the world are widely covered. These ensure that articles published in JIM have the maximum exposure to the international scholarly community.
JIM can help its authors let their papers reach the widest possible range of readers, and let all those who share an interest in their research field be concerned with their study.
